Because high-purity alumina has a plate-like crystal structure, when the current is too large, the material heats up, and the high-purity nano-alumina coating material with plate-like crystal structure will expand in volume, closing the current conduction holes on the lithium battery separator. , thereby blocking the current.
Advantage 1: When the current is too large, it can block the current. The lithium battery separator made of PP/PE material is a through hole. When the current is too large, it can easily cause perforation, which will cause the lithium battery to burn or explode. High-purity alumina (VK-L500G) is used as the coating material and adhesive When used together with the agent and coated on the surface of PP/PE materials, it can adjust the pores. This is because high-purity alumina has a plate-like crystal structure. When the current is too large, the material heats up, and then the high-purity nanometers with plate-like crystal structure The alumina coating material will expand in volume and close the current conduction holes on the lithium battery separator, thereby blocking the current. When the temperature drops, the material volume will shrink, and the current conduction holes on the separator will It will reopen. Using the special physical and chemical properties of this material, the safety performance of lithium batteries can be greatly improved, thus providing the possibility for high-energy, safe and reliable charging and discharging of high-power lithium batteries.
Advantage 2: High-purity nano-alumina (VK-L500G) also has very excellent thermal conductivity. When the battery temperature is too high, this material can conduct heat well, thus solving the problem of poor thermal conductivity of PP/PE materials.
Advantage 3: High-purity nano-alumina (VK-L500G) material also has excellent flame retardancy. This is because the high-purity alumina material itself is a very good flame retardant. Even if the temperature is too high, it reaches the zero point of combustion. , the material's good flame retardant properties will prevent large-scale combustion or even explosion.
